Explanation:

Turning Moment Diagram:

  • The turning moment diagram is also known as the crank effort diagram.
  • It is the graphical representation of the turning moment or torque or crank effort (Y-axis) for the various position of the crank (X-axis).
  • The area under the turning moment diagram gives the work done per cycle.
  • The work done per cycle when divided by the crank angle per cycle gives mean torque Tm.
